125-Ton Hydraulic Compression System for Overhead Conductors |
Power Line Pressing Tool Kit
Product Description
The 125-Ton Hydraulic Compression System is a high-performance
pressing solution designed for overhead conductor installation and
transmission line jointing. Engineered for heavy-duty applications,
this system ensures efficient, reliable, and precise compression of
conductors, splices, and connectors during power line construction.
The complete kit includes a 125-ton hydraulic compressor, a full
set of precision-engineered compression dies, and a high-pressure
hydraulic pump for fast and stable operation. With robust
construction, high output pressure, and excellent energy
efficiency, this system is widely used by power utility
contractors, EPC companies, and transmission line construction
teams.
Suitable for ACSR, AAAC, AAC conductors, and OPGW fittings, the
system provides consistent crimping results, ensuring strong and
secure electrical connections needed for long-distance transmission
networks.
